Intraoperative images of the allogeneic tendon transfer procedure: (1) Make an 8 cm incision at the distal end of the lateral ankle joint and separate it layer by layer to the fracture end; (2) Remove free bone fragments; (3) Ligament contractures are seen after removal of bone fragments and cannot be repaired directly; (4) Use an allogeneic tendon and braid; (5) Drill the distal end of the fibula and the tendon is penetrated; (6) Move the tendon to drill the cuboid bone and fix it; (7) Adjust the tension of the tendon and fix it at the drill hole of the calcaneus; (8) Suture the tendon body to the anterior talofibular ligament at the insertion point of the talus and strengthen the suture with the surrounding tissue; 9.The appearance improved after the ligament and tendon are sutured
